Axial Deep Groove Ball B. SKF 51108

The SKF 51108 axial deep groove ball bearing accommodates unilateral axial forces in mechanical engineering applications, with dimensions of 40x60x13 mm.

The 51108 axial deep-groove ball bearing is designed to support axial loads acting on a shaft parallel to the axis. Manufactured from standard rolling-element bearing steel (100Cr6), this SKF design guides the shaft in one direction and does not accommodate radial forces. A sheet steel cage guides the rolling elements and maintains a constant spacing between the balls. The separable design allows the shaft ring, housing ring and ball-cage assembly to be fitted separately in the specified order.

What is the 51108 axial deep-groove ball bearing suitable for in operation?

This rolling bearing is used where pure compressive forces in the axial direction need to be supported. Typical applications include vertical bearing arrangements and shaft guides in general mechanical and plant engineering. As the direction of action is single-sided, the bearing specifically absorbs axial forces from one direction. This design is not intended for alternating or bidirectional thrust forces and may require a counter-bearing.

Why is precise alignment crucial for the 51108 axial deep groove ball bearing?

The axial deep-groove ball bearing is not angularly adjustable. The mounting surfaces on the shaft and housing must be perpendicular to the axis of rotation, as the component does not automatically compensate for misalignment or shaft deflection. The product complies with the standard tolerance P0/PN (comparable to ABEC 1) and comprises the bearing unit without an additional shim. The permissible temperature range is from –30 to +150 degrees Celsius.
